Book Description
In this dissertation, I study retail product assortments and how vertical relationships between manufacturers and retailers shape the retail landscape. The first chapter studies systematically the market share dispersion of national brands in 25 consumer packaged goods industries, and investigate the role of retailers in explaining the share dispersion. We first document stylized facts that the distribution of national top brand shares are asymmetric across retailers, even for retailers competing in the same geographic market, and the "share advantage" that a leading brand enjoys within a retailer is persistent across markets where the retailer is present and stable over time. We then specify and estimate a variance decomposition model to decompose the total variance in national brand shares and product assortments into a Brand * Retailer component and a Brand * Market component. We find that 50% to 60% of the total variance is accounted for by the Brand * Retailer component, while the Brand * Market component only explains about 10% to 20% of the total variance. Our results suggest that the large market share dispersion of national brands is caused by strong asymmetries in how these brands are presented in different retailers, even under similar market conditions. Finally we provide evidence that long-term vertical relationships between retailers and manufacturers is a key explanation for the strong asymmetries in national top brand shares across retailers and geographic regions. The second chapter takes the empirical evidence documented in the first chapter one step further, and studies a specific type of vertical arrangement---category captaincy contract. Category captaincy is a vertical arrangement whereby the retailer delegates pricing and assortment decisions of an entire category to one of the leading manufacturers within the category. These confidential contracts can lead to disproportionately higher market shares for the captain's products. The objective of the paper is to infer the existence of such contracts and to quantify their impacts on prices, market shares, and profits of manufacturers and retailers. I use the yogurt category as an empirical setting, in which the captain is either Dannon or Yoplait---the top two brands in the category by national market share. Using Nielsen scanner data, I first estimate a random-coefficient model of consumer demand. I use estimates of the brand-retailer specific shocks and a Bayesian inference model to classify retailers into one of the three categories: Dannon-captained retailers, Yoplait-captained retailers, or non-captained retailers. Conditional on the classified arrangements, I then apply conduct tests to infer that captains eliminate double markups from their own products, while the non-captain products still have double markups. The results from counterfactual experiments show that category captaincy arrangements increase market shares of the captain by about 50%, but they can also increase retailer profits and consumer welfare by eliminating double markups on the captain's products.

Book Description
"In this thesis, I address two important topics in quantitative marketing: vertical relationships and ad tone effects. In the first essay, I study the impact of manufacturer-retailer relationships on the distribution of new products in the context of the U.S. hard cider market. Manufacturer-retailer relationships are often cited as an important determinant in product distribution. By coordinating the channel and aligning incentives, relationships can significantly affect both manufacturers' and retailers' profits and contribute to market concentration. However, empirical evidence is scarce because relationships are usually trade secrets. I present novel empirical evidence of mutual preferential treatments between manufacturers and retailers in assortment choices and wholesale pricing. I interpret the finding as pair-specific relationships sustained through repeated interactions, and use industry regulations on trade and wholesale pricing to address alternative mechanisms, including non-linear contracts. I estimate a structural model of consumer demand, retail and wholesale pricing, and assortment that incorporates the relationships. The results show that the relationships increase Anheuser-Busch InBev's and MillerCoors' new cider availability by 17.7% and 7.2%, respectively, and present a double win to both the manufacturers and retailers. In the second essay, we study the effects of positive and negative advertising in presidential elections. We develop a model to disentangle these effects on voter turnout and candidate choice. The central empirical challenges are highly correlated and endogenous advertising quantities that are measured with error. To address these challenges, we construct a large set of potential instruments, including interactions with incumbency that we demonstrate provide the critical identifying variation, and apply machine learning causal inference methods. Using data from the 2000 and 2004 U.S. presidential elections, we find that positive and negative ads play fundamentally different roles. Negative ads are more effective at driving relative candidate shares, whereas positive ads stimulate turnout. These results indicate that a candidate geographically targeting tone trades off local relative share gains and local increases in turnout for localities with a strong base. Counterfactual simulations indicate that ad tone alone can impact the outcome of close elections. Our analysis also provides potential explanations as to why past studies have produced mixed findings on both ad tone and turnout effects."--Pages vii-viii.

Book Description
This dissertation consists of three essays which study assortment planning and inventory management of substitutable products motivated by different practical problems. Chapter 2 considers the assortment planning problem for a retailer who faces customers that buy multiple differentiated products (n-pack) on a store visit. We develop two choice models: the probabilistic choice rule which captures the heterogeneous consumer population choice pattern and maximum choice rule which captures the homogeneous consumer population choice pattern. We find that, under probabilistic choice rule, the optimal assortment is such that it includes a certain number of the most and least popular products. In contrast, under maximum choice rule, the optimal assortment does not have a fixed structure except that it is guaranteed to include the most popular product. We develop an algorithm under maximum choice rule which is shown to have good performance. In addition, we derive the structure of optimal assortment under both choice rules when a retailer ignores key features of n-pack choice model including choice premium and basket shopping behavior. We also conduct a numerical study where we show that ignoring these key features can lead to significant profit loss for a retailer. Chapter 3 explores the assortment planning for a firm who faces a two-sided market. That is, the firm receives revenues from two distinct user groups: the customers, who pay for the products it sells and the advertisers who pay to advertise their brand to the customers. We obtain structural properties of the optimal assortment. We also consider the case where the firm is allowed to offer multiple products with the same attractiveness profile and price. In this case, we obtain conditions under which the optimal assortment is made out of distinct products. In addition, we show that ignoring the revenue from the customers or the advertisers, or focusing only on one segment when making product assortment decisions can lead to a significant revenue loss; specifically, we derive the theoretical bound on revenue loss in these situations. Chapter 4 studies the decision making of an inventory manager who needs to decide order quantities of multiple substitutable products in his store. As such, the decision maker typically checks the sales history of the products. When there is stock-out, the sales history provides inaccurate information because the lost sales are unobservable and the sales from substitution are indistinguishable from first-choice sales, which we refer to as the "doublecensoring effect". To study the impact of substitution rate and information amount on decision maker's performance, we design an experiment where subjects need to decide inventory levels for 2 substitutable products in consecutive 30 periods. The experimental data shows that subjects underestimate the demand for high demand product and overestimate the demand for low demand product. Moreover, the bias is worse when there is substitution in fully censored information treatment. Also, when subjects are provided with less information, they tend to order larger quantity in early periods in order to learn demand.
